nter the desired frequency
via the keypad.•Direct input can be set until 1 kHz digit, rotate [R-DIAL]to set
below 1 kHz frequency after set tuning steps, if necessary. (See
p. 14 for setting the tuning step.)
•Pushing [VFO MHz]omits the entry of 100 kHz and below, when
you want to edit to these digits “0.”
•Push [DUALWATCH]to cancel the entry.5. Receive mode selection➥Push [MODE SCAN]several
times to select the desired re-
ceive mode.•FM, WFM, AM, LSB, USB and
CW are available.
■Memory programmingThe IC-R20 has a total of 1250 memory channels (including
200 auto write channels and 50 scan edges) for storing often
used receive frequency, mode, etc.1. Setting frequencyIn VFO mode, set the desired receive frequency mode.•When “µ µ
” indicator is displayed, push [VFO MHz]to select the
VFO mode.2. Selecting a memory 
channelPush [MR S.MW]for 1 sec., 
then
rotate [R-DIAL]to select the de-
sired memory channel.
•“µ µ

QUICK REFERENCE GUIDE■Programmed scan operation25 pairs, 50 channels of memories are used for programmed
scan operation, that specify a scanning range. The pro-
grammed scan scans between “xxA” and “xxB” (xx=00 to 24)
frequencies. Therefore, before operating the programmed
scan, different frequencies must be programmed into “A” and
“B” channels.D D
Programming scan edgesAstart frequency must be programmed into a “xxA,” and end
frequency must be programmed into a “xxB” memory channel.1. Setting frequencyIn VFO mode, set the desired receive frequency mode.•When “µ µ
” indicator is displayed, push [VFO MHz]to select the
VFO mode.2. Selecting a scan edge         
channel “A”Push [MR S.MW]for 1 sec., 
then
rotate [R-DIAL]to select one of
the desired scan edge channel
“A.”
•“µ µ

3. Writing a memory channelPush [MR S.MW]for 1 sec. until
3 beeps sound.•Scan edge channel “B” is automat-
ically selected when continuing to
push [MR S.MW]after program-
ming.
•After programming is completed,
return to VFO indication.4. Selecting a scan edge         
channel “B”Push [MR S.MW]for 1 sec., 
then ro-
tate [R-DIAL]to select one of the
desired scan edge channel “B.”
•“µ µ
” indicator blinks.
•When the scan edge channel “B” is al-
ready selected at step 3. (continuing to
push [MR S.MW]after programming),
skip this step.5. Writing a memory channelPush [MR S.MW]for 1 sec. until 3 beeps sound.•The next scan edge channel “A” is automatically selected when con-
tinuing to push [MR S.MW]after programming.
•After programming is completed, return to VFO indication.

Starting scan 
1. Select VFO mode.Push [VFO MHz]to select the VFO mode for full, band and
programmed scan operation.•Select memory mode by pushing [MR S.MW]for memory or bank
scan.2. Selecting a scanning typeWhile pushing and holding
[MODE SCAN], 
rotate [R-DIAL]
to select one of the desired
scanning type.
•Available scan types when VFO
mode is selected; “ALL” for full
scan; “BAND” for the selected
band; one of “PROGxx” (xx=0 to
24) for programmed scan.
•Available scan types when memory
bank is selected; “ALL” for all mem-
ory scan, “BANK-LINK” for  bank-
link scan; “BANK” for the selected
bank scan.
